Inside and outside grinding machine for pipe

Abstract

The invention provides an inside and outside grinding machine for a pipe. The grinding machine comprises a working table, a pipe clamp assembly, an inside grinding assembly and an outside grinding assembly. The pipe clamp assembly comprises a pneumatic chuck, the pneumatic chuck is connected to the working table in a rotary mode, and the central axis of the pneumatic chuck is higher than the table face of the working table and parallel to the table face of the working table. The inside grinding assembly and the outside grinding assembly are arranged at the two ends of the pneumatic chuck respectively in a matched mode. The inside grinding assembly comprises an inside grinding wheel and an inside grinding motor, an output shaft of the inside grinding motor is connected with the inside grinding wheel in a rotary mode, and the inside grinding wheel and the inside grinding motor are connected the working table in a sliding mode through a first connecting frame. The outer grinding assembly comprises an outer grinding wheel and an outer grinding motor, an output shaft of the outer grinding motor is connected with the outer grinding wheel in a rotary mode, and the outer grinding wheel and the outer grinding motor are connected with the working table in a sliding mode through a second connecting frame. The inside and outside grinding machine for the pipe has following beneficial effects: the precision requirement that the inside grinding wheel and the outside grinding wheel need to be identical in rotation speed is lowered; and the occupied space of the grinding machine is further saved.

Description

technical field [0001] The invention belongs to the field of pipe processing, in particular to an internal and external grinding machine for pipes. Background technique [0002] In actual use, the connection between pipes often needs to be polished on the inside and outside of the pipe at the joint, so that the polished pipe just meets the requirements of the coupler, achieving a seamless connection of the two pipes and ensuring its tightness. [0003] However, most of the existing pipe grinding machines can only grind the inside or outside of the pipe body alone, and there are more advanced grinding machines that can simultaneously grind the inside and outside of one end of the pipe, but these devices have a common The disadvantage is that when the pipe is turned and polished, the outer grinding wheel and the inner grinding wheel must ensure the same speed, otherwise they will affect each other, thereby affecting the smoothness of the pipe grinding.
